Cozy, Cute, and Practical!
Size: Twin/Twin XL, Color: Light Pink
I got this pillow for my daughter to use when she heads off to college this fall, and she absolutely loves it! The light pink color is soft and calming, just what she wanted to match her dorm decor. It’s plush, supportive, and super comfortable, whether she's sitting up to read, study, or just relax. The removable, washable cover is a big plus, and the side pockets are so convenient for stashing her phone or glasses. While the pillow works great on its own, we still plan to get a detachable headboard to complement it for added support. Overall, this is a stylish and functional addition to her dorm setup, and we’re both really happy with the quality. Highly recommend!

Nice decor for the bed
Size: Twin/Twin XL, Color: Black
Ordered this in black and it looks nice in the bed that doesn’t have a headboard . It comes nicely sealed and once you take it out you need to keep hitting both sides to fluff it up throughout the day . This is not a firm pillow , but if left alone on the bed it holds up and looks nice . Once you lay on it then it feels like an over fluffy pillow that keeps you upright in a comfortable way . There is no smell so that as a plus . Nice decor for the bed !

Buttons
Size: King, Color: Dark Grey
Here's what I like: Appearance. I like the color and how it looks on my bed. It looks appropriate for a king sized bed. Removable cover. It was easy to take the cover off and wash, which I appreciate because I like my bedding to smell fresh and clean. What I don't like: It is a bit softer than I would like. But I can live with it. I thought it was a foam pillow inside, not fill. Maybe my fault though for not reading description or reviews. Quality. This is the biggest issue driving the rating. I removed the over upon opening the item so I could wash it. The buttons are attached the the inside cover. When removing the outside cover, you have to unbotton them. They are not secured well at all. From what I can tell the threading goes through the inside cover through the fill to the button on the opposite side. I suspect this because 4 buttons came off when I removed the outside cover. They are very loosely secured to each other. Be gentle when removing and replacing the cover. Now I will have to thread the buttons again and secure it. Just a pain for a brand new item. Should I expect that for the cost of the item? I dunno. Could have been a higher rating, but, damn those buttons.

Nicer than the pictures!
I bought this for my wife for Christmas and it’s been a game changer for watching TV in bed. I was always having to double up on pillows and having to adjust them because they’re down and kinda deflate lol. The green color is super pretty too! Quality so far has been really good!

Huge, super soft, cozy pillow!
Size: Jumbo (25-Inch), Color: Sage
This pillow is awesome! As a plus size person who can't sleep laying flat, the size and support level is perfect. This pillow is huge! The quality is very high, the stitching is precise, and the sage green material is soft and cozy. Great value for the price! I highly recommend this reading pillow!
